But I've found myself in a situation more than once where knowing that you could be having _reliable_ warnings with just a simple battery radio independent of it all was very reassuring.

[backstage] Kinect.. what if..
...all this bumpf about how fancy they are[0] is just a load bollocks. I am wondering if them Kinect things are really working a lot simpler; and after waking up in the middle of a shower am now postulating that: 1. They have a simple static laser interference pattern (e.g. akin to [1] or those star projectors you can buy from street vendors). 2. However this one is very very fine and nicely randomish. i.e. dots less than a few mm appart. 3. They use a crappy low resolution normal monochrome web cam; with a black bit of glass so only IR gets let through. 4. They simply pass the image of this camera back. The reason that this works is that every 'pixel' at CCD level for distances of working range will have 1 to 100 or so 'tiny dots' on it - depending on the distance it is at. Which is why we have roughly the range we get; why we have such a near perfect 1/sigma callibration curve and why the range of values you get it so odd - and why they filter certain types of noise so badly. And perhaps, perhaps: 5. They do a phase locked loop amplifier loop in software by flashing the projector. But I doubt that given the noise/error artifacts. And that is really all there is to it. Anyone here with a good high-res SRL which can do enough IR detection to check if indeed this is the case ? I guess a fun test would be to use a mirror to project a few extra pixels onto a flat area - and see if that area suddenly jumps 'forward'.

[backstage] [Fwd: OpenCommunity Camp 2009]
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 See below - and feel free to pass on. Nice relaxed low key week of hacking community, code and kit at a nice location just south of Amsterdam Airport - on cycling distance from of Leiden and the beach. Started as a community wifi camp - each year they get a bit more interesting and slowly grow to cover a much wider swath of open technology, content, hardware and so on. Anything from soldering up to community building around pure content like wikipedia. You generally will want to bring a tent - but last year they where also well set up if that is impractical or of the weather is bad - drop them a line. There are several indoor area with tables for the kit, sofa's and talks. Or in short - nice mix of people, lots of bandwidth and beers in the sun :) Recommended !

Re: [backstage] video cameras + sailing dingies
Tim Dobson wrote: So basically I've just acquired a small waterproof HD video camera and I'm looking for the best way to mount it onto my Laser EPS[1] sailing dinghy. It has a standard tripod mount so I was wondering about tying it on with desk tripod near the mast foot or something but I wondered if anyone had any prior experience or thoughts on how they'd do this. I found that a standard head* (or a bottlecap head**) will do OK - and it is easily mounted by swapping out the bolds of the fairlead which keep the traveller line or the cunningham for a longer one upside down (and with a washer below decks - as they have the right diameter. Also - a lot of older lasers have 4 empty/pained-over holes where you can mount a compass - on port from the horizontal runout of the cunningham. For the speed of the bold you need to go imperial though - the metric ones will ruin your camera - and if you do not use something like a standard head (which makes swapping easy) be very sure you two counter-twisted or wing nuts+plastic washer at the right distance - as otherwise you will ruin the threads of the camera. However it is not ideal - they are near the deck (but any higher and the beam/sails obsucre the view all the time) - and hence easily trown out of alignmnet or vibrating as you move around. I've had a lot of bad luck with putting them higher up; e.g. in the mast - the speed at which that will hit the water or other things seems more than the waterproofing could stand. And on salt water - it is pretty much game over if the battery has any charge left. Looking forward to your pictures.

Re: [backstage] BBC - a typical Google search on a desktop computer produces about 7g (0.25oz) of carbon dioxide
Brian Butterworth wrote: Does anyone have the working for this? I would LOVE to see it, given that (for a start): No - but willing to guess that they either took the total energy consumption and divided it - or took a reasonable number x number of servers; assumed 100watt and took it from there. a typical Google search on a desktop computer produces about 7g (0.25oz) of carbon dioxide Looking at Alexa and friends - we're talking some 1-3 10^9 of queries per day; so, say, 750 10^9 a year. So assuming about 500 gram per kWh we get something like 150 10^9 kWh/year dived by the about 10k hours in a year = 15 10^6 Watts of contineous use; say 100 watt per machine = 150k machines. So that sounds pretty low (unless I made a mistake) as every machine generally carres 1-2 extra 'machines' for cooling at the very least. Hmm - off by 10 ?
